ANTHOMYIID^E. 



BY C. H. TYLER TOWNSEND. 



This fifth and last paper of the series presents a synopsis of the 

 North American genera of the family Anthomyiidie, and concludes 

 the synoptic treatment of the Calyptrat^e. Students who contemplate 

 working in this family should consult Dr. R. H. Meade's valuable 

 " Annotated list of British Anthomyiidse," published in the " Ento- 

 moh)gist's Monthly Magazine," vols, xviii, xix and xx, and two sup- 

 ])lements in vols, xxiii, xxiv and xxv (see last jjaragraph of notes 

 to the present paperj. The same author's " Notes on the Antho- 

 myiidae of North America" (Ent. Mo. Mag. xiv, 250-52) should 

 be carefully studied. These latter are mostly reprinted in Osten 

 Hacken's "Cat. of N. American Diptera," 1878 edition. The works 

 of Rondani, Loew and Dr. Johann Schnabl will also prove of much 

 use. Many of these are scattered papers, but most of them are re- 

 ferred to in the O.-S. Catalogue, or in Dr. Meade's annotated list. 

 The following synopsis is based u})on the treatment of the genera in 

 Dr. Meade's work just referred to.
